To My Readers



If this is the first time you're visiting my blog, thank you. Whether you're interested or just curious to find out about PCB reverse engineering (PCB-RE), I hope you'll find something useful here.

This blog contains many snippets of the content in my books to provide a more detailed overall sampling for my would-be readers to be better informed before making the purchase. Of course, the book contains more photos and nice illustrations, as evidence from its cover page. Hopefully, this online trailer version will whet your appetite enough to want to get a copy for yourself.

Top Review

I started doing component level repair of electronics with (and without) schematics more than 40 years ago, which activity often involves reverse-engineering of printed circuit boards. Although over the years my technical interests have shifted into particle beam instrumentation, electron microscopy, and focused ion beam technology fields, till this day——and more often than not——PCB repairs have returned multiple multi-million-dollar accelerators, FIB, and SEM instruments back to operation, delivering great satisfaction and some profit.

Many of the methods described by Keng Tiong in great details are similar to the approaches I've developed, but some of the techniques are different, and as effective and useful as efficient and practical. Systematic approach and collection of useful information presented in his books are not only invaluable for a novice approaching PCB-level reverse engineering, but also very interesting reading and hands-on reference for professionals.

Focus on reverse engineering instead of original design provides unique perspective into workings of electronics, and in my opinion books by Keng Tiong (I've got all three of them) are must-read for anybody trying to develop good understanding of electronics——together with writings by Paul Horowitz and Winfield Hill, Phil Hobbs, Jim Williams, Bob Pease, Howard Johnson and Martin Graham, Sam Goldwasser, and other world's top electronics experts.

From Engineer to Author


Many experienced engineers prefer practical hands-on work to writing books.

Not because they're bad at writing. They do it every day—emails, reports, findings, training notes if they teach. Technical writing is part of the job. But writing a book? That's an entirely different ball game.

Besides the challenge of learning a new craft, you need to write with clarity and in an engaging manner. You can't bore your readers. You can't lose them in a jungle of engineering jargon. Engineers can state a technical fact accurately—that's what we're trained to do. Perhaps we can even state it clearly. But to write engagingly? To make someone want to read about circuits and diagnostics?

That's a skill most of us never develop.

I've often heard people say engineers are a boring lot. Lacking creativity and imagination. Stuck in left-brain thinking, unable to connect with normal humans. I wouldn't consider myself a boring person. But I'll have to admit: most people become lost whenever I tell them about my work. Their eyes glaze over. They nod politely. They look for an exit.

I've thought about why this happens. This was the new challenge I faced when starting out.

How do you translate technical expertise into prose that people actually want to read?

How do you explain complex ideas simply, without losing the depth that makes them valuable?

For engineers, this struggle is real. More real than we'd like to admit.
